Thinly slice two Spanish onions, and cook ten minutes in one-fourth cup butter, stirring constantly. Add one quart White Stock III, cook slowly thirty minutes, and strain. Dilute three tablespoons flour with enough cold water to pour easily, add to soup, and bring to boiling-point. Then add one cup cream, and one tablespoon chopped green peppers, or one-fourth cup grated cheese. Season with salt and pepper.
